Best time to go....Probably August/September. Maybe as early as June/July. The water is always very cold - too cold to swim. I've been there several times with our H 16. We stayed at Nevada Beach - South Lake Tahoe near the state line. Close to the casinos. Something to do at night.
We liked sailing & camping at Clear Lake better. The water is warmer. We camped in Lakeport.

Hi - It's been a while since we've been there. We stayed at Will-o-Point in Lakeport, CA. I still have their brochure & the phone # is/was??? (707)263-5407. There is a launch ramp nearby & we slept on our boat tramp at night. We woke up each morning to a large duck & a bunch of ducklings as they swam by our stern. Warm water, beautiful scenery, warm weather, strong wind in the afternoon, things to do & places to eat in town.
It was a perfect set-up except for the bathrooms. They were okay, but not great. I would go there often if it were closer to San Diego.
Clear lake is the largest lake in CA. Tahoe is larger, but part of it is in Nevada.
You can leave your boat set up at night at both Nevada Beach (Tahoe) & Will=o-Point (Clear Lake).
Good Luck!

I've never heard anything bad about sailing on Clear Lake or the town of Lakeport.

I spent time in Tahoe for many years. That water can be down right brutal. I f you sail there a dry suit may be in order. The winds are really strong in the afternoon, much like our bay. Have fun, but take care!
